Compared with the original connection mode, the wiring apparatus has the advantages of simplified processing technology, saved raw material and lowered cost.
Description
Technical field
The utility model is a kind of termination of omnipotent breaker, is used for being connected between circuit breaker and the outside bus-bar, belongs to the low voltage electrical apparatus technology field.
Background technology
Along with the continuous development of Chinese national economy, the transmission and distribution network capacitance also constantly increases.Omnipotent breaker occupies in low-voltage distribution system and important effect, and it is used for distributing electric energy and protection circuit and power-supply device, makes it avoid harm such as overload, under voltage, short circuit, earth fault.Simultaneously; Also in continuous rising, wherein high-performance, miniaturization have become the developing direction of omnipotent breaker to the user, in order to satisfy the requirement of user for the busbar installing space that confluxes to the demand of omnipotent breaker; Breaker connection terminal outlet direction is changed into vertical direction by level; To guarantee under the situation that does not improve the circuit breaker overall width, increase the contact area that conduction connects, improve performance of products.
The bridge type contact connection slotting tool of existing omnipotent breaker and the syndeton of binding post are as shown in Figure 7.Slotting tool and binding post are split-type structural, and slotting tool is connected through bolt with binding post.Wherein slotting tool is connected on the pedestal through mounting panel, and front end inserts the bridge type contact, and back joint face is processed a plurality of screwed holes; Process connecting hole on the binding post joint face, and be provided with transition structure.There is following defective in this structure: 1. offer screwed hole on the slotting tool, and the waste raw material, processing technology is complicated; 2. for guaranteeing resistance value between joint face, on the one hand, need to increase the joint face contact area, improve joint face Surface Machining precision, cause the rising of processing cost; On the other hand, must guarantee the required pretightning force of bolted on connection, pretightning force is excessive possibly destroy screw thread, and pretightning force is too small possibly to increase contact resistance, increases assembly difficulty and influences the properties of product reliability.
In sum, the syndeton that the bridge type contact of existing omnipotent breaker is connected slotting tool and binding post is improved and is just seemed particularly important.
The utility model content
The purpose of the utility model provides a kind of termination of omnipotent breaker, and it can reduce raw material, processing cost, simplified processing process, the reliability of enhancing product performance.
For this reason, the utility model adopts following technical scheme:
A kind of termination of omnipotent breaker comprises electric-conductor, it is characterized in that:
Said electric-conductor is one group with two, and every group of two electric-conductors are connected, and the contact-making surface that connects latter two electric-conductor is vertical each other.
Further:
In every group of two electric-conductors, an electric-conductor is provided with groove, and the joint face of another electric-conductor inserts in this groove and connects.
In every group of two electric-conductors, two electric-conductors connect through welding manner.
In every group of two electric-conductors, two electric-conductors are square, T shape or L shaped.
In every group of two electric-conductors, an electric-conductor connects L shaped mounting bracket, and this mounting bracket is connected with electric-conductor through rivet, bolt.
Attaching nut on the folding surface of said mounting bracket.
Said nut adopts welding or clinching method and said mounting bracket affixed.
The beneficial effect of the utility model is:
1. two electric-conductors connect through groove, cancel original joint face, transition structure, reduce copper consumption, reduce the cost of raw material.
2. two electric-conductors connect through welding manner, remove bolt from and connect, and it is firm to connect, and simplified processing process reduces the joint face internal resistance, helps reducing the circuit breaker temperature rise, improves reliability of products.
